Range Rover Evoque: Gradient release control (GRC)
Land Rover Range Rover Evoque L538 (2011–2018) Owner's Manual / Hill descent control / Gradient release control (GRC)
With HDC activated, if the vehicle is stopped on a slope using the foot brake, GRC will become active (except in Terrain Response Sand program). It operates in all gears and in neutral position.
During a steep hill descent, when the foot brake is released GRC will automatically hold brake force for a short period before gradually releasing it, allowing for maximum control to be retained.
During an uphill start, a similar brake hold and gradual release is employed. This allows time for the driver to apply speed and allow the vehicle to move away smoothly.
